RHH coolant

Post by jgra1 »

confused chaps..

What coolant would you refill your X7 HDI RHH with?
GSF and ECP are beyond belief... GSF are quoting £122 for a 20L bottle, ECP are quoting something called Evans Waterless coolant at £65 for 5L !!! plus £40 for pre coolant preparation

Whatever happened to something called antifreeze ;) ?

Last month, when I went to my trusted local factors I got some pink coloured G30 Extreme OAT stuff, based on my reg, at about £20 for 5L (which has leaked away due to a pipe breakage)
I will look at the owners manual as well.. but wonder why I bought something reasonably cheap from the factors before, if the two websites think I should pay a lot more?

help :)

I'd be down to the dealer - I've always bought my C5 antifreeze from them, fortunately they are close to me.
Not cheap but nowhere near those prices.

hmm
thanks Steve,

the comma G30 extreme that was sold by factors - and is available in many petrol stations - seems to be heavy duty :

for trucks, and Lamborghinis (spelling) and other..

which are similar as we know


Its a diesel engine, and already 6 years old.. it cant be so hard to keep it cool and frost free .. I long for the days of blue coolant so much! ;)

I agree, I long for the days of simplicity in all kinds of things John..

This coolant lark does seem to have become silly..

What's the big advantage of OAT coolants over the old traditional glycol ones anyway?

Is it not the case that all types will work in all modern cars from the late 80's/early 90's on ? (accepting the need to flush through to be sure it is clear of whatever was in before)

Thanks both.. can't think I have done any damage really. Will see what the dealer bottles say when they are picked up.

Allegedly, if OAT and glycol mix the resultant is a gooey and gloopy mess that can cause all sorts of fun..

If you suspect any cross-contamination the way to check, I believe, is to drain out a jamjar's worth after a quick run, let it stand for a day and see if two distinct layers settle out...

is there a problem with just flushing with a hose and then refilling with your coolant mix of choice Jim ?

Not as far as I can see, as long as the flush is very thorough indeed, including things like the matrix and any auto transmission coolers...

The main advantage of OAT is that it is more stable over time so should be good for something like five years. Either the old school green stuff or OAT can be used in any car as far as I'm aware so long as you thoroughly flush the system if you're changing types.

The waterless coolants are a totally different kettle of fish and have very specific preparation guidelines which should be followed to the letter.

They have the advantage of a far higher boiling point, meaning the system effectively will run at a lower pressure reducing the chances of catastrophic failure of hoses etc. Also gives you a bit more wiggle room on vehicles which maybe don't have the best cooling systems.

Will be looking into that stuff in more detail in the spring when I sort the Skoda out as they are quite prone to overheating, and the first thing that happens if that happens is the water boils in the head and air locks the water pump...expensive stuff though...especially as I'll need 11 litres of it!

As far as i am concerned G12+ is giid enough for VW/Audi & others so its good enough for Peugeot/Citroen. Same mix of metals plastics and rubbers in both cooling systems and very similar engine technologies. A 50-50 mix is good to -40C. I use about 33% which should cope with anything that is likely to come here and i would guess the same for England & Wales. When rechanging timing belts i have never noticed any corrosion inside the water pump cavity. Its not that often you get to do that though with intervals of 240 000KM or 10 years.
Price is about €25 for 5L of concentrate.

and G30 BX?
I started with a pretty empty system when I swapped engines, and will flush this weekend and refill with whatever the dealer gives me.. I agree really.. alloys, rubber and plastics

I really dont know anything about G30. G12 is what VW and some others demand and it does the job for me. It is available for some time and has proven itself to me. It is also affordable. 3 litres of mix (1litre antifreeze and 2 litres of water) costs me about 5 euro which is about 3.50 in GB pounds.
I did a google search for G30 and it seems it can be used to replace G12. For older machines e.g an old tractor with a complete cast iron engine and brass radiator, with more likelyhood of a leak i use the old fashioned blue antifreeze on the basis of cost as its even cheaper.
